APPLE'S share price has tumbled after the iPhone X launch as Wall Street digested the details of new phone - as well as the iPhone 8 and the iPhone 8 Plus.

Investors were on edge ahead of the iPhone X launch, amid hopes the new features would justify the gadget's $999 price tag (which is expected to sell for about £760 in the UK), 10 years after the first iPhone was released.

The tech giant's stock price jumped initially jumped after the release, but losses picked up on Wednesday, with the value sinking by around 1.5 per cent.

iPhone sales are hugely important for Apple's profits, so the X and 8 models are crucial for the technology giant's outlook.

But it's feared delays could dent profits.

Michael Hewson, chief market analyst at CMC Markets, said: "The Apple product launch went pretty much as expected with a new iPhone 8, as well as the iPhone X or iPhone 10, along with a new Apple Watch which doesn’t require an iPhone to make and receive calls.

"The new price point for the new iPhone X proved to be on point at $999, though consumers won’t see it until November due to parts scarcity.

"Having rallied into the announcement Apple’s shares closed slightly lower on the day, on disappointment over the delay to the launch."

Investors are looking for further proof that the iPhone X and 8 will boost Apple's profits - and share price higher.

Russ Mould, investment director at AJ Bell, said: "Investors looking for a windfall from shares in Apple or the companies who supply it (such as Laird, IQE and Renishaw) may need to be patient, as the new iPhone X looks evolutionary rather revolutionary, the product is not available until November and in many cases the shares have already done very well.

“Key developments in the iPhone X include a new organic light-emitting diode (OLED) screen, facial recognition, the scrapping of the home button, an enhanced camera and wireless charging – but all of these had been leaked in advance and none really represent a major step ahead of the competition.

“In addition, given the amount of preparation involved, it seems odd that Apple can’t actually make the product available until 3 November, even if British gadget fans can pre-order the £999-plus device from 27 October.

“As a result, there has to be a chance that Apple’s shares pause for breath, especially after their stunning run from $108 a year ago to $161, just shy of the $164 all-time high racked up last week.

“This would fit with both the old stock market saying about 'buying on the rumour and selling on the fact' and the trading history of Apple’s shares, which have tended to soar ahead of a product launch (as speculation gathers about what will be involved) and then run into profit-taking afterwards."

“This edge-to-edge display means that the device is missing the home button we’ve seen since the first iPhone debuted a decade ago, and users will now control the handset by swiping up from the bottom of the screen.

“However, the absence of the home button also means that the iPhone X offers no Touch ID security system, with users able to set up facial recognition via Face ID instead.

“The three new iPhones all boast a new glass front and back, making them the most durable iPhones to date, and will help protect users from unnecessary damage in their day to day lives.

“As expected, wireless charging capabilities are available across all three devices, and next year Apple will offer a new charging mat that allows simultaneous wireless charging for an iPhone, Apple Watch and the AirPod headphones."
